How to Measure Your Pet's Neck
Use a cloth style tape measure to measure your pet's neck.
Add two or three inches to the length.
Collars should be snug, but leave room to fit two
fingers between your dog's neck and the collar.
If you don't have a cloth tape measure, you can use a string or end of a leash
to measure around your pet's neck. Mark the length with pinched fingers
and lay it on a ruler or tape measure.
Other handy measuring instruments are a standard sheet of paper ( 8 1/2" x 11") or a dollar bill (2.5" x 6"). Just fold and tape together to discover the size of your pet's neck.
The images above are just for reference.
If you have a very small or very large pet, let us know, we can fit collars to any size.
